 * Trying to do the upgrade to 3.1
    I have read about all of the people who had 
   the identical issue as me..I have installed manually a couple of times already
   to no avail. Fatal error: Call to undefined function is_network_admin() in /home…../
   blog/wp-admin/admin-header.php on line 16
 * It seems like everyone solves it eventually, they all say at the bottom of the
   thread…”I solved it thanks!” But nobody states how they did.
 * How do I solve this? When I try to log-in through the admin panel, I get the 
   error.

 * Hey!
    I solved it. Thanks for the help!
 * No. really, I did solve it.
    I had my host upgrade to the suPHP. This was their
   reply when I asked about the WordPress upgrade issue: Your currently PHP version
   is 5.2.9. However you are using the DSO php handler. In order to be able to successfully
   do automatic updates you would need to switch to SuPHP, as the permissions of
   DSO and generally how it functions, while it works with WordPress not all features
   would be available (such as automatic updates or automatic installation of WordPress
   addons). I suspect the reason you are having trouble with the manual update as
   well is because of the permissions associated with DSO. Would you mind if I switched
   you over to use the SuPHP module?
 * I then did the manual upgrade again. At first it appeared that it did not work.
   It did the database upgrade..then poof, I was logged in as the admin. I am not
   exactly certain why it stalled at first and then let me in.
